This morning, WikiLeaks released part 3 of its Vault 7 series, called Marble. Marble reveals CIA source code files along with decoy languages that might disguise viruses, trojans, and hacking attacks. These tools could make it more difficult for anti-virus companies and forensic investigators to attribute hacks to the CIA. Could this call the source of previous hacks into question? It appears that yes, this might be used to disguise the CIA’s own hacks to appear as if they were Russian, Chinese, or from specific other countries. These tools were in use in 2016, WikiLeaks reported.
